Product Description
I've noticed in my Geometry classes that students struggle with the idea of what happens to the perimeter and area of a shape if you double its sides, and I've found that it's helpful for my Geometry students to consider several shapes, determine their areas and perimeters, and then repeat the calculations for shapes in which all sides are doubled, tripled, etc. This is the resulting worksheet.

This worksheet "holds their hands" as they look into this issue. It asks them to explain their predictions and test them.

The file includes spiral review problems, such as exponents, which actually come in handy for this sort of exercise.

It is intended that students write directly on this worksheet.

Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may edit for your students.
